Magnetoplasma excitations in interacting GaAs disks
S. A. Andreeva, A. A. Gavrilov, K. R. Dzhikirba +5
We investigate the effect of inter-disk coupling on the magnetoplasmon dispersion in a square lattice of two-dimensional electron system (2DES) disks etched from a GaAs quantum wel…
The inherently absent 2-dimensional electron gas in ultra-pure GaN/AlGaN heterostructures
S. Schmult, S. Wirth, V. V. Solovyev +5
Gallium nitride (GaN) has emerged as an essential semiconductor material for energy-efficient lighting and electronic applications owing to its large direct bandgap of 3.4 eV. Pres…
Friedel oscillations as an origin of Mahan exciton/Fermi edge singularity phenomena in optical spectra of degenerated semiconductors
V. V. Solovyev, I. V. Kukushkin
We point out at the possible relationship between the two many-body phenomena: Friedel oscillations and Mahan exciton/Fermi edge singularity in a recombination process of a localiz…
Detection of 2D electron g-factor sign inversion in narrow GaAs/AlGaAs quantum wells
V. V. Solovyev, W. Dietsche, I. V. Kukushkin
By means of CW polarization-resolved photoluminescence spectroscopy we demonstrate the sign inversion of -component of 2D electron g-factor with narrowing of a hosting GaAs/Al…
Light-hole quantization in the optical response of ultrawide GaAs/AlGaAs quantum wells
V. V. Solovyev, V. A. Bunakov, S. Schmult +1
Temperature-dependent reflectivity and photoluminescence spectra are studied for undoped ultra-wide 150 nm and 250 nm GaAs quantum wells. It is shown that spectral features previou…
Measurement of binding energy of negatively charged excitons in GaAs/AlGaAs quantum wells
V. V. Solovyev, I. V. Kukushkin
We report a photoluminescence study of electron-hole complexes in specially designed semiconductor heterostructures. Placing a remote dilute layer of donors at different distances…
